[edit] List of Operators

[edit] General

Operator	- Description
Type	- Get the ProcessTypeID of a ProcessType or define a new datatype. See Type.
. (period)	- Element access. `<struct>.<element>`. In case of a struct array, if no arrayelement is specified, it points to [0] (see example).

[edit] Maths

Operator	- Description
+	- Addition.
-	- Deduction
*	- Multiplication.
/	- Division.

[edit] Logic

Operator	- Description
\|\|	- OR. One or the other or both.
&&	- AND. Both.
^^	- XOR. One or the other, but not both.
!	- NOT.

[edit] Bitwise

(Logical operation per bit.)

Operator	- Description
\|	- BOR. One or the other or both.
&	- BAND. Both.
^	- BXOR. One or the other, but not both.
~	- BNOT.
<<	- Bitshift left, causes bits to move left a certain number of positions.
>>	- Bitshift left, causes bits to move right a certain number of positions.

[edit] Memory

Operator	- Description
&	- OFFSET. Get the memory address of a variable. See pointer.
*	- POINTER. Get access to the variable a pointer is pointing to. See pointer.

[edit] Example

Type _point
    int x;
    int y;
End

Global
    int int_1 = 1;
    int int_3 = 3;
    int int_4 = 4;
    int someint = -5;
    String somestring = "AAP";
    String anotherstring = "BEER";
    byte somebyte = 6;
    signed byte sbyte = -2;
    byte b_5 = 5;
    byte b_12 = 12;
    Struct Person[9]
        string name;
        int age;
    End
    _point myPoint;

    person[0].name = "Mies"; //

    person[1].name = "Aap";
    person[2].name = "Noot";
    // ...etc...
    person[9].name = "Last person"; // last array element

    setXY(&myPoint);

    Repeat
        frame;
    Until(key(_ESC))

End

Function int setXY(_point* p)
Begin
    p.x = 3; // this is actually (*p).x = 3, but . can be used like this
    p.y = 5; // this is actually (*p).y = 5, but . can be used like this
    return 0;
End

Used in example: say(), key(), Global, Type, Struct, Array, Pointer, period

This will result in something like:
